WTO Dispute settlement proceedings - Measures imposed by the United States on certain steel and aluminum products

On 9 July 2018, Switzerland launched WTO dispute settlement proceedings against import adjustment measures imposed by the United States on certain steel and aluminum products. Switzerland considers that these measures are contrary to WTO law. Consultations, which represent the first stage of WTO dispute settlement proceedings, failed to settle the dispute and Switzerland requested the establishment of a panel. The panel was established on 4 December 2018 and the proceedings are now ongoing. Six other dispute settlement proceedings – initiated by China, the European Union, India, Norway, Russia and Turkey – are currently under way concerning the measures taken by the United States.
